DB/Reporting :: Allow User To Back-up And Restore Database?
Apr 25, 2010
I am using VB.net 2003. I am working on a stand alone windows program that stores data in an Access database via ADO.net via MS jet 4.0 OLEDb. I have progressed to the point that I would now like to provide the end user the oportunity to back-up the data they have stored and re-install if they choose. I am envisioning a menu item for "maintenance" with sub-items for "back-up" and "restore"
I'm working on a multi user VB.Net windows application with back end as SQL Server 2008 Express. The SQL Server is installed on the intranet network drive. This is the connection string I will be using. Is this correct?
Data Source=.SQLEXPRESS;AttachDbFilename=Q:DatabasePrintDB.mdf;Integrate d Security=True;Connect Timeout=30;User Instance=True
I want to take my access database which i used in my project on visual studio2008 backup by selecting the local drive of my computer at the time of backup i choose the drive & there were i taken the backup i restore my database. Is is possible to take backup atomatically when i close my application.
I have an app written in vb2005 that allows users to search a sql database for a store name. Once a store is selected, it then presents the user with 12 different tabs, each with a DataGridView showing various bits of info about the store. It's a large and convoluted database, so I'm using stored proceedures to pull the data for each tab. Here's a sample of one of the subs that populates the tabs.[code...]
Now, this works just fine to populate the grids on the tabs, and the same code is copied into each of the subs that fill the grids (changing the stored proc, parameter and grid names, of course). The problem I'm having is how to move changes made to the data in the grid back into the database.
I have stored procs that do this (and the procs do work), I just can't seem to figure out how to trigger the stored proc when the user makes a change.
If it matters, there is only a grid on each tab, I did not use a binding source as I am trying to keep an abstraction layer between the data and the app. I did create a dataset, which is how I gain access to the stored procs, but I left the grids unbound and (as seen in my code) bind them at run time.
How to make back-up and restore point? what I want to happen is when I click the button back-up. It will generate a back-up of database in access on the current date. And if I click the button restore. the system will restore the last back-up point. So that when there is a file accidentally deleted, the system can retrieve it again.
What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
I have a utiility that users can re-order DataGridView Columns in to their hearts content. I want them to be able to create a named list so they can have multiple Column Patterns to choose from.When I restore though the re-ordered Columns are not where I saved them.
I created an executable file of an application done in VB Express 2010 which connects to a Access 2010 database. When installling the executable file at one of the user's computer, the file is installed correctly, but it fail's when trying to connect to the database. It says that Microsoft Dataengine cannot open the database. The user's computer doesn't have Access installed, does it need to be installed? or can I install a framework or application to avoid installing Access at the user's computer?
i just want some opinnion or suggestions regarding database softwares. we are going to develop a system for 20 or less users, i am planning to use MYSQL community server as our database to lessen the budget for that system, i just want to know if it is ok to use that version.is there a big differece between mysql community server, enterprise server and MS SQL Server in terms of handling data i.e security, speed, etc...
Alright, let's try this again. I have an mdb file as a database in my program, I need this mdb file to be what my published program reads off of. Is there any way to have Visual Basic (2008 Express) not encode my mdb file to Example.mdb.deploy?
I am using the Mysql .NET connect and can connect to my database using my program. i want to be able to get a Users Password from the database using there user name
This is the query i want to use: "SELECT Password FROM staff WHERE Username = " & textbox1.text & " '". But i don't know how to run that query and to get it to store the Password as a variable
Here's what I'm attempting: The user browses for and opens a dbf file. The user is presented with a checkedlistbox which shows the column headers. The user then selects the columns they wish to run a report on. ex. total # of cells not empty, longest cell length, etc.
I'm to the point of populating the checkedlistbox with all of the columns shown but I'm unsure if the users selections are actually linked to my data and if they are how I go about isolating said selections for the reports. I have a feeling that my approach to populating the checkedlistbox is not the proper way for what I'm trying to accomplish.
Here is the code
Public Sub btnGetFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetFile.Click Dim fileLookUp As New OpenFileDialog
I was thinking of an efficient way to add quarantining abilities to my antivirus application. I was thinking, which way is better: to copy the file into a specified directory and change its extension to none ("*. "). Either that or maybe I can save the file's binary code in an XML database. Which way s better?However, I have no idea how I will recompile the binary code once the user wants restore the file.

How do you restore a dataset to the previous state before updating the database with a data adapter? I have a concurrency update problem that I believe to be caused by this. The update fails during the update and a rollback command is issued using a SQLTransaction object. However, now the rowstates of the rows that did not have errors have been changed to unchanged. So this record is no longer availible to be inserted into the database. When I updated the value that could not be null and then test the second update which runs just as the first does then I get a concurrency error. The update code is below:
